I very nearly caused a similar "accident" about 20 years ago in Germany.
Driving at very late at night down the autobahn in an English van (so right hand drive) at top speed, which being English was only 63mph
The Autobahn was unlit and empty, when in the near distance I thought I spotted a single flash of a cycle rear light, surley not, this is a German Autobahn, however I was on my guard and took my foot off the accelerator, another flash, very close, I pulled very sharply into the middle lane, and passed a American soldier standing in the middle of the slow lane waving a flashing bike light ! I passed so close (me being on the 'wrong side') that I saw him move his arm in so the wing mirror missed him, just. I also read his name tag in the dark (I was very close) . Pvt. Schmidt
Up ahead was an on ramp, and there trundling down at 40mph was a long convoy of US Army lorries.
I drove the jeep at the front of the convoy, wound down the window, and as I was on the same side as the driver I pulled up very close and told him what I thought of their "traffic management". He was somewhat suprised that I knew the name of the solder, that I was speaking English on a German Autobahn and that he was the driver addressing the driver, all at 40mph.
To this day I doubt Pvt. Schmidt has any idea how lucky he is to be alive.
Had I hit him that would have been an accident on my behalf and I'm not sure what you would call the actions of the US military, "crass stupidity" would make stupid people look clever
